    • Ultrasound imaging of carotid atherosclerosis in a normal population. The Tromsø Study 

      Johnsen, Stein Harald; Mathiesen, Ellisiv B. (Journal article; Tidsskriftartikkel, 2009)
      In the Tromsø study, we have successfully used high resolution ultrasonography for assessing atherosclerosis development in a general population. The method is well suited for large epidemiological surveys. Methodological problems could be overcome by using highly standardized protocols, pre-study training of sonographers and readers, and off-line computer-based batch reading of digitized images. ...
